musicxml2ly produces unexpected EOF in .ly file

Victor Rouanet
Good morning,

I'm having an issue with musicxml2ly, installed with a manually
downloaded version on lilypond 2.19.82.

I exported a musicxml file from Musescore, then converted it to lilypond
source with musicxml2ly without error. However, when I try to compile it
with lilypond, I get the following error: "syntax error, unexpected end
of input, expecting \header". Here is the full output:
https://hastebin.com/raw/navufewufu

And the musicxml file content: https://hastebin.com/jafanosumu.xml

This error happened with any musicxml file I tried to convert from
Musescore.

After some research, I found this topic on the lilypond-user list
http://lilypond.1069038.n5.nabble.com/XML-to-ly-and-Lilypond-again-td203101.html 
which looks like exactly the same.
The suggested workaround (replacing
split_string_and_preserve_doublequoted_substrings by string.split in
musicexp.py:139) makes it work, but I'm wondering if I'm doing something
wrong.

Victor

Which operating system are you using?

On Linux, I don't get any EOF error.
Find attached the .ly file generated by musicxml2ly version 2.19.82.
There's a wrong input though:

Re: musicxml2ly produces unexpected EOF in .ly file

In reply to this post by Victor Rouanet
I was planning to report this.  What's happening is that strings are being converted to 16-bit Unicode instead of UTF8, and so they are interspersed with nulls.  If you remove the nulls with a capable editor, then that issue goes away (you can do it with Frescobaldi, but it's non-intuitive - copy part of a string into the replace dialogue, the nulls appear as spaces, delete everything except one null then replace with nothing throughout the file).


Other issues:


The line

        \mergeDifferentlyDottedOn\mergeDifferentlyHeadedOn
which occurs in the score section for each stave causes the bar-checks to fail (I don't get why, but that's how it is), so it would be nice to be able to turn that off.


Also, the score is full of explicit \stemUp and \stemDown commands, which it would also be good to be able to omit.


Finally, I don't know why, but the conversion fails for me on any XML generated by Sibelius 7.5 (the version I have) or MuseScore (current).  In both cases, I can read them into Dorico which can then rewrite them in a way that the Lilypond converter reads successfully.

Please let us know your operating system and LilyPond version.
Can you also attach the problematic .ly file?
Thanks

Victor, please keep the list in Cc.

I was using lilypond packaged by Fedora, which uses python2 installed
on the system (currently 2.7.15).
I've now installed 2.19.82 from lilypond.org, which uses the bundled
python .
There's something wrong:

$ file jafanosumu.ly
jafanosumu.ly: data

There's some bad encoding. See attached file.

$ ls -lh ~/.local/lilypond/usr/bin/python*
-rwxr-xr-x 2 fede fede 5,1K 24 giu 14.11
/home/fede/.local/lilypond/usr/bin/python
-rwxr-xr-x 2 fede fede 5,1K 24 giu 14.11
/home/fede/.local/lilypond/usr/bin/python2.4

It's just my installation?
This release had also some problems in the PDF manuals...

Same result for me. According to Phil Homes in the lilypond-user topic,
the shlex module (used by musicxml2ly in utilities.py) didn't support
unicode input prior to Python 2.7.3. That would explain why the
conversion only fails with manually downloaded version of lilypond,
which bundles python 2.4.5.
When I hand edit the musicxml2ly script, forcing it to use the system
python version (2.7.13), the result file looks well encoded.

$ file -i jafanosumu_converted_using_python2.*
jafanosumu_converted_using_python2.4.5.ly: application/octet-stream;
charset=binary
jafanosumu_converted_using_python2.7.13.ly: text/plain; charset=us-ascii

According to David Wright*
I misread.

So we should upgrade Python in GUB?

I hope more people will be able to run GUB successfully. Only Phil can
run it at the moment?
I look forward to Knut's patch.

Your GUB patch has been sitting on the 'to push' list for a few weeks now.

Can you make the pull request please to https://github.com/gperciva/gub 
so that Phil can merge your changes into GUB?

Thanks

James
